The Haas 2CA, a Single Stage to Orbit (SSTO) rocket, is able to launch 100 kg (220lbs) of payload into low earth orbit at $1million/launch. The rocket has an exceptional mass ratio and it has one stage that is fueled by hydrogen peroxyde and kerosene. The SSTO configuration is made possible by the use of:

- dense propellants;

- advanced fabrication tehniques for the composite propellant tanks;

- the Executor linear aerospike engine that promises optimum performance at virtually all flight levels, allowing the use of up to 30% less fuel than any other rocket engine;

- the thrust vectoring control achieved by throttling 8 out of 16 combustion chambers, eliminating the heavy and complex gimballing system for the engine.

ARCA's Haas 2CA Single Stage to Orbit (SSTO) rocket uses a linear aerospike engine. The aerospike engine was extensively tested on the ground by NASA and Rocketdyne and it was a strong contender for the Space Shuttle. It was also part of NASA’s VentureStar, a Single Stage to Orbit vehicle. Due to schedule and budget constraints, the Space Shuttle received a classic bell shaped nozzle engine and the VentureStar was canceled before getting to see an actual flight. Therefore the aerospike engine never saw a space flight to this day. In March 2017 however, ARCA Space Corporation brought this technology back to the public’s attention, by introducing the Haas 2CA Single Stage to Orbit rocket, equipped with the Executor Aerospike linear rocket engine.

Haas 2CA will operate on the nano/micro satellites market which is based on a SpaceWork and Eurostat forecast indicating 3,000 satellites between 1- 50kg will require a launch between 2016-2022. The total market value is estimated to be $5.3 billion in the next decade. At $1,000,000/launch the Haas 2CA perfectly fits into this market seeking economical solutions.

Demonstrator 3 is a suborbital rocket that is used as a test bed for the Haas 2CA Single Stage to Orbit (SSTO) rocket. Both Haas 2CA and Demonstrator 3 use coomposite tanks and pressure fed linear aerospike engines. Demonstrator 3 will be launched from Spaceport America, New Mexico in October 2017.

Soon we are going to know if the hopes and dreams of generations of aerospace engineers, in their pursuit to create what is supposed to be the most efficient rocket engine in the world, will materialize. We hope to confirm that rocket engines that are significantly more fuel efficient than the current engines are achievable. If so, they can lead the way to the creation of Single Stage to Orbit rockets, that are more cost efficient and responsive.
